C# isn’t exactly compiled, at least not into machine language. It is transpiled into byte code that is run on a virtual machine that on turn is an interpreter/JIT-compiler.

Depending on why someone is asking for a compiled language that may or may not be a problem, because to the one writing the code it looks like a compiled language, but to the one running it it looks like an interpreted one.

And which country are you from that you think you are entitled to throw the first stone?
